WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 567,868, dated September 15, 1896.

Application filed April 15, 1896.

To all whom it may concern:

Be it known that we, ALBERT EDWARD SnvroNs and EDWARD HIXoN, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved ater-Heater, of which the following is a full, clear, and exact description. I

The object of the invention is to provide a new and improved water-heater which is si1nple and durable in construction, and more especially designed for heating feed-water for boilers in a very simple and economical manner by the use of live steam or exhaust-steam, or both. 7

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is an enlarged perspective View of the live-steam outlet-cap, and Fig. 3 is a like view of the water-inlet and exhaust-steam outlet-cap.

The improved water-heater is provided with a pipe A, connected with a pump, water-main, or other suitable source of water supply, said pipe being connected with a cap B, held on the outer end of a Water-pipe 0, preferably made in the form of a coil, as is plainly indicated in Fig. 1, said pipe discharging at its upper end into a cap D, connected by a pipe E with the boiler, to deliver the heated water to the same. The exhaust-steam pipe F passes centrally through the cap D and centrally through the coil 0, so that the exhaust-steam travels in the inverse direction to that of the water passing through the coil.

The pipe F is provided near the entrance of the cap D with an oil-separator G, containing a deflecting-plate G and a corrugated baffle-plate G on which the oil accumulates and flows down by gravity into a receptacle II, provided with a gage H and a draw-01f cock H for emptying the vessel H from time to time of the accumulated oil. Next to the oilever desired.

Serial No. 587,666. (No model.)

trally through the cap B at the lower end of the coil G, to then connect with a verticallydisposed exhaust-pipe I, having its upper branch I discharging into the atmosphere, the said branch 1 being adapted to be closed by a valve 1 to cause the exhaust-steam to pass downward into a branch I and from the latter by a pipe J to a steam-trap K, of any approved construction.

The lower end of the branch 1 is provided with two valves 1 1 and the extreme lower end of said pipe is adapted to discharge into a sewer or other place. The pipe 1 between the valves I I is connected by a pipe L with a receiver N for receiving the water of condensation, the said receiver being provided with an outlet-pipe N, adapted to connect with a pump for forcing the water in and through the pipe A, to return the water of condensation to the boiler by said pipe A and the water-pipes O and E. The receiver N is also provided with a valved outlet N adapted to connect with the city main or other source of water supply for supplying the receiver N with water in case a vacuum exists therein.

The water-pipe C is surrounded by a steam pipe 0, which may serve as a steam-jacket and which is adapted to connect with a livesteam pipe I to pass said steam through the said pipe 0 in the inverse direction of the flow of the water passing through the pipe 0. The li ve-s team pipe P is provided with a valve 1? and is adapted to be connected with a branch pipe P having a valve P connected with the exhaust-steam pipe F, so that by closing the valve P and opening the valve P part of the exhaust-steam may be passed through the branch pipe P into the pipe 0 to assist in heating the water flowing through the pipe 0. The lower end of this steam-pipe O terminates in a cap Q, provided with an outlet-pipe R, connected with the pipe J, for passing the steam to the trap K. The pipe R is provided with a downward extension R, discharging into the pipe L, leading to the receiver N, so that any water of condensation can pass through the said pipe R to the pip L and to the said receiver N. I

In the pipe L are arranged the valves L and L on opposite sides of the pipe R, to permit of running the water of condensation either to the receiver or condensers N or to 2 se'aeeg the lower end of the pipe 1 connected with the sewer.

The pipe J is provided with two valves J J 2 on opposite sides of the pipe R to permit of controlling the flow of the steam or water of condensation to either the trap K, receiver N, or pipe I. The trap K is provided with an outlet-pipe S, having a valve S, controlled by a float S in the said trap K, so that when the water rises therein the float S will open the valve S to permit the accumulated water to pass out through the pipe S, either to a suitable place of discharge or through a branch pipe T into the reservoir N. The pipe S is provided with a valve S and a similar valve T is arranged in the branch pipe T for controlling the flow of water either to the outside or to the reservoir N. Now it will be seen that by the arrangement described the water to be heated flows in one direction, while the steam surrounding the water-pipe and the steam passing in a pipe through the water -pipe flow in opposite directions, so that the feed-water is gradually heated, as it first is subjected to the steam having a low degree of temperature, and is finally subjected to steam of a high degree of temperature, so that when the feed-water reaches the cap D it is at a very high temperature. Now it will be seen that by the arrangement described live steam and exhaust-steam can be used for heating the feed-water in the manner described, or, if desired,the live steam can be shut oit and exhaust-steam passed both through the inner pipe F and the outer or check pipe 0.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent 1. A water-heater, comprising a water-pipe connected with a suitable source of water supply and with the boiler, a steam pipe or jacket surrounding said water-pipe, a steampipe passing through said water-pipe, the steam passing through said pipes flowing in an opposite direction to the flow of the water passing through the water-pipe, a live-steam pipe connected with one end of said outer steam-pipe, and an exhaust-pipe connected with the said inner steam-pipe, substantially as shown and described.

2. A water-heater, comprisinga water-pipe connected with a suitable source of water supply and with the boiler, a steam pipe or jacket surrounding said water-pipe, a steampipe passing" through said water-pipe, the steam passing through said pipes flowing in an opposite direction to the flow of the water passing through the water-pipe, a live-steam pipe connected with the said outer steam-pipe, an exhaust-pipe connected with the said inner steam-pipe, and awater-receiver adapted to be connected with the outlets of said steampipes, to receive the water of condensation, substantially as shown and described.

3. A water-heater, comprisinga water-pipe connected with a suitable source of water supply and with the boiler, a steam pipe or jacket surrounding said water-pipe, a steampipe passing through said water-pipe, the steam passing through said pipes flowing in an opposite direction to the flow of the water passing through the water-pipe, a live-steam pipe connected with one end of said outer steam-pipe, an exhaust-pipe connected with the said inner steam pipe, a steam-trap adapted to be connected with the outlets of the said steam-pipes, a receiver adapted to be connected with the outlets of said steampipes, and means for controlling the flow of the steam and water of condensation to said trap and receiver, substantially as shown and described.

4:- A water-heater, comprising a water-pipe adapted to be connected with a source of water supply and with a boiler, a live-steam pipe or jacket surrounding the water-pipe, an exhaust-steam pipe passing through said waterpipe, a steam-trap connected with the outlets of the steam-pipes, and a water-receptacle adapted to be connected with the outlets of the said steam-pipes and with the trap, substantially as described.

5. A water-heater, comprising a water-supply pipe, a live-steam pipe or jacket surrounding the water-pipe, an exhaust-steam pipe passing through the said water-pipe, a steamtrap, a valved pipe connecting the trap with the outlets of the said steam-pipes, a receptacle for the water of condensation, a valved pipe connecting the receptacle with the said outlets, and a valved pipe connecting the trap with the receptacle, substantially as described.
